Do you mean like when an interface (tun? or ppp?) goes down? Since I'm
not using user ppp anymore, I wrote a simple shell script that I call
from my /etc/crontab to do this kind of stuff. The heart of it contains:
ifconfig -au | grep ppp0 >/dev/null || {
# the interface just went that way
pppd call ISP
}

Nah, running it so many times will probably make it a cpu hog. Try to
fix the problem even deeper, where it's root may be hidden.
